His words must be interpreted by their reference to the light which was then being celebrated. Of that light we read that “the Lord went before them by day in a pillar of cloud, to lead them the way, and by night in a pillar of fire, to give them light.” This was a customary mode of directing the movements of large bodies of men, whether caravans or armies. In the case of an army a tall pole was erected in front of the chief’s tent, and from it a basket of fire was suspended, so that the glare of it was visible by night, and its smoke by day. The head of a marching column could thus be descried from a great distance, especially in wide level tracts with little or no vegetation and few inequalities of surface to interrupt the view. The distinctive peculiarity of the Israelitish march was that Jehovah was in the fire, and that He alone controlled its movements, and thereby the movements of the camp. When the pillar of cloud left its place and advanced the tents were struck, lest they should be separated, from Jehovah and be found unfaithful to Him. During the whole course of their sojourn in the wilderness their movements were thus controlled and ordered. The beacon-fire that led them was unaffected by atmospheric influences. Dispelled by no gales, and evaporated by no fiercest heat of the Eastern sun, it hovered in the van of the host as the guiding angel of the Lord. The guidance it gave was uninterrupted and unerring; it was never mistaken for an ordinary cloud, never so altered its shape as to become unrecognisable. And each night the flame shot up, and assured the people they might rest in peace.
Two obvious characteristics of this guiding Light must be kept in view.
1. God’s people were not led by a road already made and used, and which they could have studied from beginning to end on a map before starting; but they were led day by day, and step by step, by a living guide, who chose a route never before trodden. In the morning they did not know whether they were to go forward or back, or to stay where they were. They had to wait in ignorance till their guiding pillar moved, and follow in ignorance till it halted. Our passage through life is similar. It is not a chart we are promised but a guide. We cannot tell where next year or next month may be spent. We are not informed of any part of our future, and have no means of ascertaining the emergencies which may try us, the new ingredients which may suddenly be thrown into our life, and reveal in us what till now has lain hidden and dormant. We cannot tell by what kind of path we shall be led onwards to our end; and our security from day to day consists not at all in this, that we can penetrate the future, and see no dangers in it, but our security is that we shall always be guided by infallible and loving wisdom. We have learned a chief article of human wisdom if we have learned to leave to-morrow to God and faithfully follow Him to-day. A road as it lies in the distance often looks impassably steep, but as we approach and walk it step by step, we find it almost level and fairly easy.
